Highlights•A light-induced one-pot coupling of PROTAC-like molecules•Cyclic ethers used as linker precursors without any pre-assembly procedure•Reactions complete within 4 h up to 95% yield with a high regioselectivity•A wide substrate scope gave triazole-based linkers structural diversitySummaryProteolysis-targeting chimeras (PROTACs) are powerful approach for targeted protein degradation. One the current bottlenecks developing PROTACs is lack an operationally simple linkerology rapidly construct various linkers. The classic convergent synthesis strategy by pre-assembled two ligands stepwise commonly needs at least four steps give final target PROTACs, which results in low total yields long reaction times (several days) and tedious operations. Here, we develop efficient photocatalytic rapid analogs containing linker-pre-assembled procedure. was completed room temperature. Easily accessible cyclic directly furnish fashion, including alkenyl, polyethylene glycol (PEG), ketone, cyclohexane chains. study provides highly efficient, step-economic, simple, environmentally friendly PROTAC drug discovery.Graphical abstract

Herein, a one-pot domino catalyzed three-component process is described, which initiated by palladium/zinc cooperatively cycloaddition between trimethylenemethane (TMM) and unactivated alkyl/aryl imines, followed isomerization Zn(OTf)2-catalyzed DDQ oxidation, furnishing valuable substituted pyrroles. We disclose that the cooperative catalysis affords dual-Zn(OTf)2-stabilized azapalladacycle, wherein Pd–N bond polarized Zn(OTf)2, facilitating unique outer-sphere allylic amination. Moreover, subsequent dehydrogenation can be feasibly promoted zinc catalysis.

Abstract Novel synthetic methods for P-chirogenic four-coordinate pentadentate organophosphorus compounds are described. The pathways commenced with the use of phosphates bearing a binaphthyl group and their congeners. These underwent reactions fluoride ion, metal hydroxides, alkoxides, Grignard reagents, resulting in transfer axial chirality from to central phosphorus atom. As result, products incorporating were obtained. substitution these newly formed alkoxides reagents led formation phosphates, phosphonates, phosphinates, some sulfur isologues.
